The government of Ethiopia has made an ambitious plan building a carbon-neutral and middle-income economy by 2030. In 2016, the country pledged to restore 15 million hectares degraded landscapes as part African Forest Landscape Restoration Initiative (AFR 100). A total three major forest landscape restoration (FLR) initiatives have been used achieve this target: participatory management (PFM) engage communities in sustainably managing natural forests; area enclosures/exclosures (AEs)...
Abstract Climate‐related environmental and humanitarian crisis are important challenges in the Great Horn of Africa ( GHA ). In absence long‐term past climate records region, tree‐rings valuable proxies, reflecting variations complementing prior to instrumental era. We established annually resolved multi‐century tree‐ring chronology from Juniperus procera trees northern Ethiopia, longest series yet for . The correlates significantly with wet‐season r = .64, p < .01) annual .68, regional...
Attempts to mitigate global climate change have brought forestry into focus. Forests absorb carbondioxide from the atmosphere, alleviate warming and contribute for rural livelihoods. To realize these benefits, there is a need conserve existing forests establish new by using different restoration techniques. Information scarce in Ethiopia on carbon stock efficiency of forest types. Therefore, this study focused comparing biomass soil potential natural forest, exclosure Eucalyptus plantation....
Seed production, seed dispersal and seedling establishment are relevant life phases of plants. Understanding these processes their patterns is essential to recognize vegetation dynamics apply it forest restoration. For Olea europaea Schefflera abyssinica, fecundity was estimated using randomized branch sampling. were monitored spatially explicit traps plots. Dispersal functions calibrated applying inverse modeling. O. produced more seeds had longer distances compared S. abyssinica....
Abstract Farmers’ climate perceptions are responsible for shaping their adaptive responses and thus essential to consider the design of strategies reduce vulnerability increase resilience. In this study, we collected social data in four communities central Ethiopian Highlands on farmers’ adaptations using group discussions PRA tools. We related these spanning 30 years (1981 2010), consisting daily minimum temperature, maximum temperature precipitation, modelled global databases regional...
Exclusion of grazing animals and tree plantations are 2 methods that have been used for restoration degraded lands in tropical semiarid areas. These options can foster secondary forest succession by improving soil conditions, attracting seed-dispersal agents, modifying microclimate understory growth. We compared native woody plant diversity chemical physical attributes under exclosure on Eucalyptus globulus (EGP) Cupressus lusitanica (CLP) plantations. Vegetation data were collected an...
The scale of deforestation in sub-Saharan Africa underscores the need for forest restoration. Information is scarce evidence-based restoration options. Sown Senna didymobotrya, planted Ficus thonningii cuttings, sown S. didymobotrya and F. combined, previously occurring native non-browse shrubs (NNS) were compared their effect on selected plant nutrients occurrence Olea europaea subsp. cuspidata north-west Ethiopia. treatments applied to experimental units established previous grazing land....
Fine root turnover of trees is a major C input to soil. However, the quality litter influenced by morphological traits and tissue chemical composition. In this study, fine roots ten tropical woody species were collected from an Afromontane forest in northern highlands Ethiopia. The analysed for chemistry measured as proxy carbon fractionations. Based on stem increment, 10 divided into faster- slower-growing species. Faster-growing exhibited higher specific length (1362 cm g−1) than (923...
Boswellia papyrifera woodland provides considerable economic, ecological and socio-cultural benefits in the drylands of Ethiopia. However, its populations are rapid decline due to human pressure environmental degradation. As a consequence, species is now considered being endangered, demanding an urgent conservation intervention sustain existence. This study was carried out Abergele district, northern Ethiopia, with objectives characterize current population structure B. prioritize potential...
Qimbaba, a prioritized forest area in the northwest of Ethiopia. However, it is experiencing deforestation that limits restoration possibilities. Hence, detailed assessment soil seed bank composition and regeneration potential could permit to improve management forests. The study aimed at comparing native with plantation relative bank, as well their effect on properties. A total 40 circular sample plots (314 m2) were established, half natural Aboveground vegetation was recorded each plot....
